MIXER Filed Jan. l5, 1934 Patented Sept. 3, 1935 UNITED STATES PATENTOFFICE 3 Claims.

This invention relates to mixers, and has special reference to mixers ofthe type useful in the operation of mixing beverages and other liquids;and objects of the invention are to provide an improved mixer having amotor provided with a vertical shaft, and an agitator operated by saidshaft, said motor and agitator being supported by a bracket mounted forvertical sliding movements on and along supporting guides, which alsofunction to limit extent of vertical movement of the bracket; to providea device for supporting the bracket in a raised or elevated position; toprovide a switch device for controlling supply of electrical energy tooperate the motor; to provide a handle in connection with the bracketdisposed between the supporting device and the switch device in such arelationship that the thumb of the hand engaging the handle mayconveniently release the supporting device and also operate the switch;and to provide an agitator of novel construction.

Other objects and advantages of the invention will be apparent from thefollowing description, reference being made to the annexed drawing, inwhich- Fig. 1 is a side elevation of my improved mixer.

Fig. 2 is an elevation at right angles to that of Fig. 1, a part of thesupporting bracket being in section.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.

In the embodiment shown, the base I is designed and intended to supporta container for the beverage-to be mixed. A vertical rod 2 has its lowerend rigid with the base I. A rod 3 has a lateral extension 4 on itslower end and a similar lateral extension 5 on its upper end, saidextensions 4 and 5 being rigidly attached to the rod 2 and constitutingabutments limiting extent of vertical movement of the bracket thatsupports the motor and the agitator, while the rod 3 cooperates with therod 2 to support and guide said bracket.

The bracket mentioned is made of a strip of metal bent to form a lowerportion 6, an outer side portion 1, a top portion 8 and a downwardlyextended inner portion 9 having its lower end forming a socket Ireceiving the reduced end I I of a handle I2 and attached to the arm 6by a fastener bolt I3.

The arm 6 and the top portion 8 of the bracket have holes through whichthe rods 2 and 3 extend. Thus, the bracket is supported and guided inits vertical movements, extent of downward movement being limited by theextension 4 of the rod 3 and extent of upward movement be- :ng limitedby the extension of said rod. An angular latch member comprising an armI4 and a downwardly extended arm I5 is pivotally supported by the upperend of the rod 2 by a pivot I6 mounted in said rod 2 and extendingthrough the arm I4 on the latch member. The lower end of the arm I5 isprovided with a shoulder I1 designed and adapted to engage under theupper part 8 of the bracket and thereby support the bracket in its upperposition. The arm I4 has an engageable portion I8 located in position tobe conveniently engaged by the thumb of the hand that engages the handleI2 so as to release the latch device from the bracket.

A motor I9 is mounted on the arm 6 of the bracket and has a switch 28located in position to be conveniently engaged by the thumb of the handof the operator that engages the handle I2 so as to control supply ofelectrical energy to the motor through the wires 2|.

The motor shaft has a downwardly extended socket 22 receiving the upperend of a rod 23 releasably held in connection therewith by clamping setscrews 24. The lower end of the rod supports a hollow conical agitatorhaving numerous openings 25 through the wall thereof separated bymembers 26 having their lower ends integral with a ring 21. The agitatoris a unitary structure and the conical upper end thereof is attached tothe lower end of the rod 23.

Fig. 1 shows the bracket and the motor and the agitator in their lowerpositions, while Fig. 2 shows said parts in their upper positions.

From the foregoing the operation of the device should be apparent.

The construction and arrangement of the parts may be varied within therange of equivalent limits without departure from the scope of theappended claims.

I claim:

1. A device of the character described comprising a vertical rod, abracket mounted for vertical sliding movements along said rod, a secondrod supported by said first rod and holding said bracket from turningabout said first rod and limiting extent of upward and downward movementcf said bracket along said first rod, a handle attached to said bracketfor moving said bracket vertically, and an agitator device supported bysaid bracket.

2. A device of the character described comprising a vertical rod, abracket mounted for vertical sliding movements along said rod, a secondrod rigidly supported by said first rod and holding said bracket fromturning about said rst rod and limiting extent of upward and downwardmovement of said bracket along said rst rod, a handle attached to saidbracket for moving said bracket vertically, a motor supported by saidbracket adjacent to said handle, an agitator device operative by saidmotor, and a control device for said motor operative by the thumb of thehand that engages said handle.

3. A device of the character described comprising a vertical rod, abracket mounted for vertical sliding movements along said rod, a secondrod supported by said rst rod and holding said bracket from turningabout said rst rod and limiting extent of upward and downward movementof said bracket along said first rod, a handle attached to said bracketfor moving said bracket vertically, a motor supported by said bracketadjacent to said handle, an agitator device operative by said motor, acontrol device for said motor operative by the thumb of the hand thatengages said handle, and a latch device supported by said rod forsupporting said bracket in an upper portion, said latch device beinglocated in position for operation by the thumb of the hand that engagessaid handle.
